SPECIFICATION forming part of Letters Patent N0. 766,941, dated August 9, 1904.

Application filed January 4,1904. Serial No. 187,713. (No model.)

To all whom it may concern:

Be it known that I, DUDLEY E. EDDLEMAN, a citizen of the United States, residing at Weatherford, in the county of Parker and State of Texas, have invented a new anduseful Metal- Shearing Device, of which the following is a specification.

This invention relates to implements for shearing metal, more particularly for severing the bands of cotton-bales, but which may be employed for any other purpose for which it is adapted, and has for its object to produce a device of great power and force which may be cheaply manufactured and readily adapted for the heaviest or lightest work; and the invention consists in certain novel features of construction, as hereinafter shown and described, and specified in the claims.

In the drawings illustrative of the invention, in which corresponding parts are denoted by like designating characters, Figure 1 is a side elevation of the preferred form of this improved device. Fig. 2 is a bottom plan View. Fig. 3 is an end elevation of the implement. Fig. 4 is a detail View of the forward or operative end of the stock, illustrating its construction. Fig. 5 is a view similar to Fig. 1, illustrating the cutting-plate reversed. Fig. 6 is a side elevation of amodified form of the invention, and Fig. 7 is a front elevation of this form of the machine. Fig. 8 is a view similar to Fig. 6, illustrating a still further modified form of construction. Fig. 9 is a plan view of the structure shown in Fig. 8.

The improved implement shown in Figs. 1 to 5 comprises a stock or body portion 10, having a handle 11 of any suitable form at one end and an inclined hook-shaped jaw 12 at the other end, the inner side of the jaw having a shear-plate 13 connected detach-ably thereto, as by screws 14, and spaced from the inclined end 15 of the stocl;,whereby a V-shaped recess 16 is formed transversely of the stock and inclined rearwardly or toward the handle 11, as shown.

The stock is provided with spaced longitudinal guideways 17 18, the guideway 18 extending in advance of the inner end of the V- shaped recess 16, as shown. Slidably disposed be quickly adapted for action upon difl'erent between the guideways .1718 isa blade 19, having a relatively long inclined cutting or shear edge 20 at one end and a relatively short and reversely-inclined. cutting or shear edge 29 at the other end, as shown more clearly in Fig. 5. The blade 19 is slidable between the guideways 17 18 and reversible therein, so that its oppositely-located cutting edges may be alternately operated in conjunction with the shear-plate 13, as will be obvious.

The relatively long shear edge 20 causes an object placed in the recess 16 to be severed from within outwardly and with a correspondingly long inclined shearing cut, while the shorter or more abrupt shear edge 29 causes an objectto be severed from without inwardly and with a correspondingly short or abrupt shear cut.

The longer shear cut will be employed where the greater resistance is encountered, as the longer cut is the more powerful, while the more abrupt action will be more desirable where less resistance is encountered. Then again the arrangement whereby the cutting action is imparted from within outwardly will be employed upon flat objects, such as bands and similarly-formed objects, while the ar-.

5 forms of materials and without change in the structure except to simply reverse the position of the plate 19.

The plate 19 is provided with a longitudinal gear-rack 21 along one edge, and the stock 10 is provided with a gear-segment 22 pivoted thereto, as at 23, for engagement with the rack and provided with an operating-handle 24:, as shown. A keeper-bar 25 is disposed over the plate 19, being connected by one end to the pivot 23 and by the other end to the guideway 17, as by screw 26. The keeperbar is provided with an integral arm 27, ex-

tending in an inclined position substantially in alinement with the inclined end 15 of the stock 10 and connected to the guideway. 18,

as by screw 28, adjacent to the inner end of the recess 16, as shown. By this simple arrangement the plate 19 is firmly supported and held not only from lateral movement by the keeper-bar 25 and its inclined arm 27, but from transverse movement by the guideways 17 18, and especially by the latter, whose forward end is projected beneath the plate adjacent to the recess 16, in which the cutting operation takes place, thus supporting the plate where the greatest transverse thrust and strain occurs and where the greatest support is required. The inclined arm 27 also performs an important function in this'respect, as the lateral support is imparted at a point nearest the end of the plate where the cutting action for the time being occurs.

The improved device shown in Figs. 6 to 9 comprises a base portion 30, having an integral standard 31 extending therefrom at an angle to its horizontal plane and offset therefrom, as shown in Fig. 7, and provided with a shear-blade 32, horizontally disposed opposite a V-shaped recess 33, as shown.

Integral with the standard 31 are spaced guideways 34 35, and slidably disposed between these guideways is a plate 36, having a shear-blade 37 attached to its free end for 00- action with the shear-blade 32 upon the base member 30. The cutting edge of the shearblade 37 is at right angles to the longitudinal plane of the member 36, and consequently acts diagonally or with ashear cut relative to the stationary blade 32, as will be obvious. The guideway 34 is provided with an opening 38 and pivoted at 39 to the standard 31, and operating through this opening is a gear-segment 40 for engagement with a gearrack 41 upon the plate 36. The segment 40 is provided with a socket 42 for an operatinghandle 43. Extending across the plate 36 is a keeper-bar 44, connected at one end to the guideway 35, as by screw 45, and connected by the other end to the pivot 39 at the segment 40, as shown. The keeper-bar thus serves a twofold purposefirst, as a support for the pivot 39 and segment 40, and, second, as a support to the plate 36 to prevent lateral movement thereof. By this simple arrangement a very compact, strong, and efficient shearing device is produced by which a shearing cut is produced upon the metal being cut by a direct-acting movable jaw member, thus elimi- -nating lateral thrust or strains, as the resistance is almost entirely longitudinally of the movable jaw.

In Figs. 8 and 9 a modified form of the structure is shown, consisting in inclining the standard 31 and slidable plate 36 reversely to the position shown in Fig. 1 and with the segment 40 and rack 41 located at the opposite side of the plate 36 and of the standard 31; but this will not be a departure from the principle of the invention or sacrifice any of its advantages, as the mode of operation and results produced are the same in both forms of the structure illustrated.

In the modification shown in Figs. 8 and 9 the operating-handle 43 is so located that the operator stands in the rear of the machine while operating it, which may be found advantageous under some circumstances. A machine of great force and power may thus be constructed of comparatively light materials, which is compact and strong and the parts thereof arranged and combined to exert the maximum offorce with the expenditure of the minimum of power.

Generally the base member will be erected upon a bench or stand of convenient size, and the machine may be adapted for severing bands or bars of metal of various sizes and may be constructed of any required size or capacity required.

The machine will be found especially adapt- M ed forsevering cotton-bale bands and similar articles while being manufactured, wherein it is frequently desired to sever the bands in bundles or in numbers at the same time and requiring a relatively strong machine to accomplish it.

With this simple device as many of the bands may be severed at the same time as the V-shaped recess will hold.

Having thus described the invention, what I claim is 1. In an implement of the class described, a stock having at one end a rearwardly-inclined V-shaped recess provided with an inclined cutting-blade and with spaced longitudinal guideways, a plate slidably disposed between said guideways and having inclined cutting edges at the ends for coaction with the cutting edge of said blade, and provided with a longitudinal gear-rack, a lever-arm pivoted to said stock and provided with a gear-segment for engagement with said gear-rack, and a keeper embracing said plate and connected to said stock at opposite sides thereof, substantially as described.
